NettoNull

NettoNull is a term used in German-speaking countries to describe a concept in road traffic law. It is one of the minimum distances that drivers must maintain between their vehicle and the vehicle ahead. The term "Null" means "zero" in German, referring to the minimum distance allowed between vehicles.

According to German road traffic law, the NettoNull distance is one of the three distances that drivers must maintain between their vehicle and the vehicle ahead. The total distance consists of three parts: the following distance, the safety distance, and the NettoNull distance. The NettoNull distance is the minimum distance that must be maintained between vehicles, and it is typically measured in meters.

In Germany, the Federal Highway Research Institute (BASt) has published guidelines for the minimum following distances that drivers should maintain. These guidelines recommend a minimum NettoNull distance of 30 meters at speeds below 100 km/h, and 30-60 meters at speeds above 100 km/h. Drivers are expected to adjust their following distances based on road conditions, weather, and traffic.

Studies have shown that maintaining a safe distance between vehicles can reduce the risk of accidents and improve traffic flow. However, the exact distance required for safe following can vary depending on a range of factors, including road type, weather, and vehicle speed. The use of technology such as adaptive cruise control has also raised questions about the relevance of traditional following distances in modern transportation.
